Cu/Zr binary metal organic frameworks: Heterogeneous catalysts for the efficient solvent-free CO2 fixation via cyclic carbonates synthesis |
초록 |
Anthropogenic emission of waste CO2 gas has reached frightening levels in the biosphere, and is suspected to be causing global warming. Thus, the development of CO2 capture and sequestration/storage technologies that involve catalyst-mediated reactions such as CO2 capture, transportation, and storage is essential. MOFs are a new and emerging class of porous material that have been dynamically investigated as catalysts for the synthesis of cyclic carbonates owing to its greater CO2 affinity. In this study, binary MOFs with HKUST-1 and UiO-66 have been synthesized using solvothermal method. The synthesized binary MOF is investigated for its catalytic efficacy in the synthesis of cyclic carbonates from epoxides and CO2. The UiO-66/Cu-BTC binary MOF provides high conversion rates of epoxides to cyclic carbonates with >99% selectivity. The appreciable conversion of ECH with the UiO-66/Cu-BTC/TBAB system was influenced by the synergistic effect of the Cu and Zr metals and the Br ion from TBAB. Based on our previous DFT studies and experimental inferences, a plausible reaction mechanism for the binary MOF-catalyzed epoxide-CO2 cycloaddition reaction was proposed. |
